Technology

Developing market-driven and cost-effective solutions for the future.

Subsea 7 has a strong portfolio of technologies to meet current and future subsea development challenges. We own one of the largest and newest groups of patents in the SURF and Life of Field market segments. We will continue to invest through the life cycle to develop new enabling and cost-reducing technologies.

 

Pipeline Bundles

Subsea 7’s track record includes the successful design, fabrication and installation of over 80 pipeline bundles around the world.

The Pipeline Bundle neatly incorporates all structures, valve work, pipelines and control systems necessary to operate a field in one single product, delivering considerable value and potential cost savings for a wide range of applications, including High-Pressure / High-Temperature field developments. 

Flowline Systems

High performance and cost-efficient Flowline Systems to enable optimal field architecture.

Subsea 7 has been successfully installing electrical heating systems for over 10 years, including the world’s deepest open loop Direct Electrical Heating (DEH) system.

Alongside the fabrication and installation of Pipe-in-Pipe solutions, we have developed one of the most efficient heating technologies: the Electrically Heat Traced Flowline (EHTF).

A key challenge for new subsea developments is maintaining the right temperature within the pipeline infrastructure to reduce the risk of blockage from hydrates or wax. Advances in heated pipe technologies, such as the EHTF, provide a solution to managing flow assurance, overcoming the challenges of longer distance tie-backs and greater water depths, in a cost-effective way.

Riser Systems

Riser Systems that meet the ever increasing challenges of deepwater and harsh environments.

Our aim is to maintain our industry leadership in riser systems through the continuous development of our existing solutions and with the addition of new riser concepts.

Riser Portfolio

Subsea 7’s riser portfolio includes proven decoupled riser systems, such as the Single Hybrid Riser (SHR), the Hybrid Riser Tower (HRT) and the Buoyancy-Supported Riser (BSR). These systems have been successfully applied to major deepwater projects.

Coupled riser systems include Flexibles, Steel Catenary Risers (SCRs), both applied on numerous fields, and Steel Lazy-Wave Risers (SLWR), with the first installed SLWR system deployed on the BC-10 project in Brazil.

Our wide range of riser solutions enable us to support clients in selecting the most suitable option for each project, taking into account field characteristics like water depth and environmental conditions.

Subsea Processing

Subsea Processing (SSP) aims to move the entire, or parts, of topside processing facilities to the seabed. SSP can incorporate a number of different processes to help reduce the cost and complexity of developing an offshore field.

The subsea challenge

Temperature and pressure conditions in export pipelines can cause flow assurance issues like hydrate or wax formation leading to the blockage of flowlines and the subsequent arrest of production. The normal flow assurance mitigation strategy so far has been to maintain temperatures above the hydrate and wax formation temperatures.

SSP technologies address such flow assurance issues at source, reducing slugging and the need for chemical injection.

SSP provides the ability to increase recoverable reserves and further enhance the economic viability of projects by optimising production.

New field development solutions

We are working in collaboration with our alliance partner OneSubsea to develop integrated subsea solutions that will add real value for our clients.

Life of Field and Remote Intervention

Developing the future of Inspection, Repair and Maintenance through innovation.

Our life of field solutions are built on our core strengths: Remotely Operated Vehicles (ROVs), survey and inspection, performance monitoring, data management, tooling and repair solutions, engineering and production sampling.

We are challenging ourselves to look for innovative integrity management technologies that will optimise maintenance activities and lower the Total Cost of Ownership.

Swagelining

Polymer lining technology for pipeline and riser systems.

Internal corrosion is one of the most common causes of premature pipeline failure. Swagelining help pipeline owners gain greater long-term certainty by protecting pipeline and riser systems from internal corrosion with integrated polymer lining system solutions.
